Application filed February 24, 1e21, Serial No. 447,394.

1 0 all to 710m at concern: Be it known that I, HOWARD Fonns'r Goning at 'Fredericlzstown, in the countyfof Knox and State of @hio, have invented a new and useful Crane, of which the following is a specification.

This invention comprehends certain new and useful improvements in wor: holding devices, and it has for its primary object a novel apparatus designed particularly for use in hoisting an en ine out of a motor vehicle and holding it in such position that a mechanic may Work thereon to advantage,

although it is to be understood that the inaXis whereby theworl; to be operatedupon' may be conveniently raised to-and held'at f the desired elevation andwhile thus held may be turned to diiierent positions by partially rotating thearm thereby making all 4 parts of the work easily accessible. v

A still further object of the invention is an apparatus of this character which is devoid of the-usual overhead crane arm or hoisting" chains or cables, the device thereby economizing space. and making itusetul in positions where an overheadarm would be in the way.

A; still further object of the invention is an improved work elevating and holding crane in which the manually operable parts are disposed in convenient relation to each other whereby a single workman may easily manipulate both the shaft for raising; and

lowering therarriagc andthe shaft for. par- .willg more tullyappear as the description proceeds, the invention consists of certain constructions, arrangements and combinaj tions of the parts that I shall hereinafter fully describe and claim, reference being which SUCH, a citizen of the United States, IQSIClpieces 14.' H 1 v The guides 7 are disposed in 'pairs, one pair of guidesfslipporting bearings 15. shaft 16 is journaledin the bearings A.

drum 17 is'secured to the shaft and islocated had to the accompanying drawings in Fi gure 1 shows,inelevation, a device 'constructed in accordance with the invention; Figure'Q is an elevati'onwher'ein the device is viewed at right angles to the showing of Figure 1; Figure 3 is a section on theline T0 been 0.

Figure 5 is a section on the line 5 5 of- Figure 3. Thecrane comprlses a :trame 1 including a base2 from whichja standard 3 extends vertically. The base 2 embodies longitudinal bars 4, connected by crossbeams 5, and

supported on castors 6, to the end that the frame may be trundled about. The standard 3 is ,made up of guides 7, connected by upper cross plates 8, thje plates 8 supporting ties 9. The guides 7 are connected at their lower ends by cross plates 10 secured'to the beams-5 ofthe base 2. Upright braces 1.1 extend between the bars 4 or the base and the forward guides 7. Horizontal braces 1-2 connect the bars a of the base with 'thelower plates 10 of the standard 3. The guides 7 are united intermediate their endsby cross between the bearings 15.- The shaft 16.1nay' be operated by, a removable crank 18.' A latch 19 is pivotedto'one guide "7 .and .is

adapted to be swung over into supporting relation with ,respectto a stop. 20. on the said guide. See 2. l vhen the, latch 19. is supported, on the stop 2 0,th'e latch proand the drum 17 againstrotation, The

E22 andthe ratchet wheel 21. are of iise. when the cranlc 1S (which cooperates with the latch 19) 1S removed, and when afiner adiustment is desired, than ca be obtained by permitting the crank 18 to swing through an arc of three hundred and sixtydegrees, into engagement with the'latch 19.

The crane embodies a vertically movable an intermediate bar 26 and a lower bar 27.

The side rails 24 are connected at the back side of the carriage. by a tie 28. A hearing plate 29 is secured'to the intermediate bar 26 and depends therefrom. Fig. 4. The bars 26 and 27 are connected by a bearing plate 30. Offset brackets 31 are mounted on the intermediate bar 26 and extend upwardly to the top bar 25. Sheaves 32 are journaled on the brackets 31' and the top bar 25. A sheave 33 is supported for rotation between the ties 9 of the main frame 1. A sheave 34 is supported for rotation in bearings 35 erected on the ties 9. One end of a I ca le or other flexible element 36 is secured as shown. at 37 to the parts 9. The flexible element 36 is looped downwardly around one sheave 32 on the carriage, upwardly around the sheave 33 on the frame, downwardly around the other sheave 32 on the carriage, and upwardly around the she-ave on the frame, the outer end of the flexible element being made fast to the drum 17.

Shafts 33 are journaled in the side rails 24 of the carriage 23 and carry rollers 39 disposed between the guides 7, the rollers having flanges 40 which, cooperating with the inner surfaces of the guides 7 (Fig. 1), aid in holding the carriage 23 for right line sliding movement in the guides 7. Tne shaft 41 is located parallel to the shafts 38 and is iournaled in'the members 24 of the carriage The shaft 41 may be operated by a de tachable crank 42. V A worm 43 is mounted onthe shaft 41 within the contour of the carriage 23. The worm 43 meshes with a worm wheel 53 secured to a work supporting shaft 44 disposed at right angles to the shaft 41. An upwardly inclined supporting plate 46 is connected at its lower end to the lower bar 27 of thefcarriage. Hangers 47 extend between the outer end of the plate 46' and the bar 26 of the carriage. The hangers 47 are connected to the plate 46 by securingelements 49 supporting a bearing 48. The armor shaft 44 is journal'ed in the bear ing 48, in the bearing'plate 30, and in the bearing'pla-te 29. The parts 46 and 47 may be described briefly as a bracket projecting outwardly from the carriage 2% and. support ing the shaft 44 for rotation. Endwise movement of the shaft 44 is prevented by a set collar 45 on the shaft, engaging the beari ng plate 30, and by the hub of the worm wheel 53, the hub cooperating with the bear- The engine which is to be repaired is clamped to the cross head 51 by the element 52. The shaft 16 rotated by means of the crank 18. The flexible element 36 traverses the sheaves 32 andisreelcd on the drum l7. Tn this way, the carriageiii. together with the engine, is raised, the rollers 39 moving between the guides 7. The carriage 23 is held in any position towhich it may have been elevated, either by engaging the dog 22 with the ratchet wheel 21, or by swinging the latch 19 into the path of the crank 18.

The shaft 41 may be rotated through the medium of the crank 42, the worm 43 and the worm wheel53 rotating the shaft 44,

the ends of the cross head 51, and 'consequently the ends of theengine, being swung; around in vertical plane. The cross head 51,. further, may be swung onthe pivot element 50. I

The crane affords a simple means whereby an engine may be hoisted off the frame'of amotor car and be disposed in a position which is convenient for the workman.
